How do I move my license to a new computer?

To begin the process, please fill out and return a PyroSim and/or Pathfinder license transfer request document to support@thunderheadeng.com. Once this is received, Thunderhead Engineering will associate the license keys to the new host information and send you a new license file.

Either of these actions will affect the computer identification information and it is therefore the same as transferring a license to a new computer.

Why do I receive License Copy Error “Could not copy license file to Local License folder.”?

The “Application Data” folder must be properly junctioned to the C:\ProgramData folder. Test and fix your Application Data junction with the following instructions:

To open a shell window, type cmd.exe in the Windows “search” box

To navigate to the ProgramData folder, type the following and press enter.
cd C:\ProgramData and press enter

To list junction points in the directory, enter the following text.
dir /aL

You should see “Application Data” in this list. If it’s missing, you can remove any bad junction, and create the good one with the following two commands.
rmdir "Application Data"
mklink /j "Application Data" C:\ProgramData
